Subject [jira] [Commented] (HBASE-12220) Add hedgedReads and hedgedReadWins metrics
Date Thu, 09 Oct 2014 21:58:35 GMT

    [ https://issues.apache.org/jira/browse/HBASE-12220?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14165832#comment-14165832

stack commented on HBASE-12220:
-------------------------------

bq. nit: The commented stuff in the test 's #doPread method commented in hdfs as well [1].
Have an short explanation?

None beyond what is in the comment already -- that the counts don't add up. Some issue in
original HDFS test.

> HDFS-5776 added hedged reads.  HBase installs should enable it. This JIRA is about exposing
hedged read metrics so they sit by all other hbase metrics. The counts are actually buried
and hard to get at in dfsclient.
